Got this in my email today. Can any of the techies on the forum confirm or refute this??
Some Broadband Facts (True?) (No)
NBN Broadband Facts
I am a network architect for one of Australia's largest Telcos - so I speak with some authority on this issue...
<snip>
I wouldn't employ that guy if he thinks that it can't be done.
In my opinion:
The author is obviously quite biased against the NBN.
1. I haven't heard of the degradation of fiber in this way. If you were really worried about it your could deliver fibre to the node and then DSL2 from the street to the house and still get 24Mbps to every house.
People don't roll out fibre to the house or fibre to the node as they need to make money out of it. Generally they also have to provide a copper phone service to each house, so there is no real advantage. I believe there have been estates that have had fibre included in their development but without the rest of the network to back it up, it becomes little better than ADSL.
2. You can deliver 100Mbps to each house, although initially you will receive similar speeds to the high speed services today, but this would increase quite quickly. You would find that providers of local Aus internet servers would bump up their bandwidth as its now cheaper. Laurie would find that what he pays for bandwidth now will drop and he will get much faster links for the same price.
The internet also has things called caches that cache information from a server and can repeat that to other users. This means you can have a file from the US that is stored locally and local users can access it at whatever speed their ISP allows. This is bread and butter technology even now.
3. A roll out of another DSL technology is never 'no cost to the tax payer'. They will pay for it through their ISP. Even if there are newer technologies, why bother when there is an existing faster one around?
4. 4G wireless will be interesting. At the end of the day, the provider of these services need to make money out of it, and it will eat into their existing voice revenue. Don't expect it to arrive soon or to be cheap. Don't expect an actual 100Mbps throughput.
5. This is just complete BS. I could do it. Funnily enough NBN Co are hiring people with my skill sets to actually do it. Telstra are not a glowing example of how to build a network, given that they have different objectives.
"Telstra to pick up the pieces" sounds a bit arrogant. They have experience at rolling out geographically big networks, but I think it is not going to be that hard for anyone else. Since fiber became cheap and the access to properties were opened up to competition, there have been a lot of providers that can offer fast services. I think AGL do this, and I think the rail network does as well, as they both have extensive pipelines and tracks which makes it very easy to run fiber networks.
